Regex Match and Retrieve Class Methods...

[farhan_ghazali]

Hi guys,

I really need your help, been trying to figure out how to do this.

I want to retrieve the name of an object methods...but i just want the name...and i also don't want to retrieve __construct()

$lines = array (
    [0] => 'public function __construct()';
    [1] => 'public function approved()';
    [2] => 'public function index($test)';
); 

I don't know anything about regular expressions...

i.e. from the line "public function approved()", I just want to retrieve "approved" and "public function index($test)", would get me just "index"

It would be nice if it won't return me "__construct()"

I really need help here...

Easiest way would be to load the class definition and then use get_class_methods(). Stripping out the __construct() takes a few more lines.

<?php
require_once 'ErrorHandler.php';
$methods = get_class_methods('ErrorHandler');
$methods = array_values(
   array_filter(
      $methods,
      create_function(
         '$str',
         'return(strpos($str, "__construct") !== 0);'
      )
   )
);
print_r($methods);

thanks your reply NogDog....

however, our application is under MVC environment and almost all of our Controller class name is Admin (admin.php)....

when i try to require_once() another admin.php from another module...it will give me an error....

that is why I wanted to try to read the class file.....and search for methods...

Here's an idea: calling the script via the CLI so that it never has more than one class defined at a time. (I'm trying to avoid a regexp solution, as it requires that you think of every syntax possibility, whereas this does not.)

main script (can be called via URL):

<?php
// path to the CLI PHP executable on your server
define('PHP_PATH', 'C:\wamp\bin\php\php5.2.9-2\php.exe');

// path to the get_methods.php script that will get the methods
define('SCRIPT_PATH', './get_methods.php');

// array of classes to be processed
// class_name => path/to/class_name.php
$classes = array(
   'ErrorHandler' => './ErrorHandler.php',
   'RssDoc' => './RssDoc.php'
);

// let's do it
$results = array();
foreach($classes as $class => $path) {
   $cmd = sprintf(
      '%s -f %s %s %s',
      PHP_PATH,
      SCRIPT_PATH,
      $class,
      $path
   );
   $results[] = array(
      'class' => $class,
      'path' => $path,
      'methods' => unserialize(shell_exec($cmd)));
}

// show the results
echo "<pre>";
print_r($results);
echo "</pre>";

The get_methods.php script which is called via CLI:

<?php
/**
 * Get the method names for a specified class
 * Meant to be called via command line (CLI)
 */

// make sure we got enough args:
if($argc < 3) {
   $usage = 'USAGE: /path/to/php ' . __FILE__ . ' ClassName /path/to/class_file.php';
   fwrite(STDERR, $usage);
   return(0);
}
// do the parsing:
require_once $argv[2];
$methods = get_class_methods($argv[1]);
$methods = array_values(
   array_filter(
      $methods,
      create_function(
         '$str',
         'return(strpos($str, "__construct") !== 0);'
      )
   )
);
// output serialized array as the result:
echo serialize($methods);

Output:

Array
(
    [0] => Array
        (
            [class] => ErrorHandler
            [path] => ./ErrorHandler.php
